IMPROVEMENT IN HOEING-MACHINES.

Specification forming part of Letters Patent No. 168,105, dated September 28, 1875; application filed February 13, 1875. 1

To all whom it may concern:

Be it known that I, HORACE N. PROUT, of

have invented a new and Improved Hoeing- Machine, of which the following is a specification:

Figure 1 represents a top view of my improved hoeing-machine; Fig. 2,-a front elevation, partly in section, on the line or m, Fig. 1; Fig. 3,. a detail bottom view of the adjustable supporting-plate of the outer hoestock, and Fig. 4 a detail side View of the bifurcated hoe-stock.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved hoeing-machine; and consiris, mainly,'in the arrangement of a number of wing-springs or hoes, which are attached to the bifurcated stocks, connected by. adjustable arms and in an adjustable manner to a tongue and gig-frame, or operated by handles. The outer wing-springs are adjusted toward the inner wing-springs on the frame bya sliding and slotted staple-plate, in connection with a fixed screw-bolt. The main frame is set to a greater or-less depth of hoes by a central pivoted lever set to different angles of inclination by slotted staples and clamp-screws.

In the drawing, A represents the main which is hung to a beam or tongue, B, and a wheeled gig-frame, B, in such a manner that it may be raised and lowered from the drivers seat by any of the approved regulating devices. The hoeing-machine may, however, also beoperated by means of handles with out a wheeled frame, in which case the main frame is attached directly to the tongue.

Frame. A is made of strong lateral pieces 0, to which the adjustable hoe or wing-spring stocks are applied, and of forwardextending brace-pieces D, that are centrally pivoted below the tongue, and applied to a longitudinal lever, E, which is pivoted intermediately between the same.

The hoes or wing-springs F are riveted or shaped ends of the bifurcated hoe-stocks F, Fig. 4, and are connected by their vertical main rods a, seated in the front arms of the stocks F, to the lateral front piece (3, by the curved rods 1) to the rear pieces 0, and by the front brace-rods d, moving in eyes of the stocks, to the front part of the bracepieces D.

The peculiar shape of the wing-springs F is specially adapted to the work of hoeing and covering which they have to perform, and has heretofore been patented by me under date of March 24, 1874, No. 148,845.

Two wing-springs and stocks are, preferably, arranged at each side symmetrically to the longitudinal axis of the machine, of

which the inner stocks are made adjustable inheight by sliding in guide staples 0, while the outer stocks are, furthermore, adjustable in lateral direction to throw the outer greater hoes into lesser distance from the inner wingsprings. bifurcated arms a b and the front brace-rod d, at three points, being firmly retained in the required positions, after adjustment, by suitable eyebolts, washers, and nuts. The front brace-rods d are applied to slotted slidepieces 01, which are separately guided andsecured by suitable set-screws. The main arm of the outer stocks F is bent at right angles below the front piece 0, and hung to staples or eyes f of a slotted slide-plate, f, which is laterally adjusted and secured by a washer, screw-bolt, and nut, f The curved rear arm of stock F slides 'in the eye of a bolt, 9, which follows the lateral adjustment of stock F in a slot, 9, of the rear piece 0. The wing-springs may thus be readily set to different widths of rows, and hung to greater or less depth, as required.

The-whole series of wing-springs may be worked at a greater or less depth by means of the central pivoted lever E, which swings higher or lower in slotted guides h of front piece 0, and is rigidly secured thereto in the required position by a fastening screw-bolt and nuts, 71/.

The ready adjustability of the hoe-stocks, in connection with the effective disposition and shape of the Wing-springs, producesavery useful, economical, and rapidly-working hoelug-machine.

Having thus described my invention, 1

Each stock is supported, by the claim as new and desire to secure by Letters frame and tongue, and adjustable at the rear Patentin slotted guides h h, as and for the purpose 1. The combination, with spring-hoes F, specified. of double-soeketed stocks F, adjustable by HORACE N. PROUT.
